Another datapoint for based upon my ownership of a June 2016 built MS90D, AP1 for little over 6 years and about 69k miles.
Only you can determine your economic value of free supercharging. For me about 45% of my total miles charging is via superchargers on long range trips. One of the difficulties in valuing that is the ever changing pricing structure for supercharging, which Tesla doesn't easily make visible, especially if you have free supercharging and don't actually see any pricing even if you look at a supercharger in the NAV system. If I look at what those miles would have cost charging at home, multiple by a factor of 3 or 4, I still only come up with something like $2-3K savings over 6 years. I'll admit, one of the reasons I've held off replacing my MD90D is the though or losing this free supercharging benefit, but that's more an emotional, psychological response. The cold hard numbers say it's less than what many pay on custom wheels, PPF or color wrap, tints, etc., or even just getting a non-standard interior/exterior color combination.
I do fully agree with
@bmah comment about AP1 for highway driving. I find it really solid, generally predictable, and meets my needs very well for my long range travel use case. I'll admit there was a bit of "oh man, I really lost out" reaction when AP2 was announced just 3 months after getting my car, but that again has played out as largely an emotional reaction, and as much as the geek in me would love all the bells and whistles of FSD at the moment, it honestly wouldn't improve my driving experience (some would argue it would degrade my driving experience given the greater propensity to phantom braking).
While I won't argue that the supercharging speed of my MS90D is as fast as a new MSLR or even a 2019-2021 model, on my MS90D it is actually faster than when I first got my car. While you will hear all the chargegate comments about owners with 85 packs (which I do not dispute) for my mid-2016 90 pack I cannot claim any indication of throttling. At a V3 supercharger, I see upwards of 150 kW when my battery is up to optimal temperatures and SOC in the 25-30% range. Here's data from earlier this spring/summer at a few different locations in the midwest. My total charging times at a typical stop are same or a few minutes faster than back in 2016-2017. I am currently at about 8.5-9% apparent range degradation, around 268-270 miles on a full charge vs the 294 rated when new.
I've commented in some other posts about my out of warranty maintenance experience, but other than a couple door handles, recently replacing the 12V battery, and electing to upgrade to MCU2, I've not had any issues. I do have 1 headlight where the DRL "eyebrow" is yellowed/dimmed (three replaced under warranty) but I view that as cosmetic, not functional failure, and have elected to not replace (I put that money into MCU2 upgrade instead!).
